Description
Overview
The GE Optima MR450w GEM 1.5T redefines patient experience and diagnostic precision in whole-body magnetic resonance imaging. Built on GE’s redesigned wide-bore hardware platform, the system bridges the gap between patient-friendly wide-bore designs and the ultra-sharp resolution traditional $1.5\text{T}$ systems deliver.
At the core of the Optima MR450w is the GEM Suite, an approach to RF coil design that utilizes flexible, lightweight arrays designed to contour naturally to the human body. Coupled with OpTix Digital RF technology, which converts analog RF signals into optical signals right inside the magnet room, the system eliminates traditional signal degradation over cabling, delivering crisp, high-SNR images across all clinical specialties.
Key Features & Advanced Technologies
-
70 cm Wide Bore & Short-Magnet Geometry: Flared opening with bright interior LED lighting significantly reduces patient claustrophobia, easily accommodating bariatric, elderly, and pediatric patients.
-
GEM (Geometry Embracing Method) Suite: High-density, ultra-lightweight coils (Head/Neck Unit with Comfort Tilt, Flexible Anterior Array, and embedded Express Table Posterior Array) designed to conform seamlessly to body contours.
-
OpTix Digital RF System: Converts analog RF signals into optical digital data directly inside the scan room, maximizing signal clarity and suppressing ambient electronic noise.
-
IntelliTouch Patient Positioning: Streamlines workflow by enabling technologists to set up exams in as few as 30 seconds simply by touching the target anatomical site on the table.
-
Advanced Non-Contrast & Silent Imaging: Supports GE’s Inhance non-contrast angiography suite, 3D ASL perfusion mapping, and SilentScan technology to dramatically reduce acoustic gradient noise to near-ambient room levels.
